Protein
Methane monooxygenase regulatory protein B
Gene
mmoB, MCA1196
Organism
Methylococcus capsulatus (strain ATCC 33009 / NCIMB 11132 / Bath)
Status
Reviewed - Annotation score: 2 out of 5 - Experimental evidence at protein leveli

Functioni

The B protein acts as a regulator of electron flow through the soluble mmo complex, switching the enzyme from an oxidase to a hydroxylase in the presence of the substrate.
